Abstract
Adhesion between materials is often governed by the ambient environment, which can mediate or change the types of molecular interactions present at an interface. Biological interactions, for example, can be mediated by factors such as temperature, ionic strength, and pH. In light of these considerations, we have been developing an in situ aqueous adhesion test based on Johnson, Kendall, and Roberts (JKR) contact mechanics, and here we present results from measuring the pH-dependent adhesion of poly(dimethylsiloxane) (PDMS) hemispheres coated with layer-by-layer assemblies of polyelectrolytes to silane-functionalized glass. Our results suggest a comprehensive understanding of all surface properties is necessary for understanding and predicting adhesion at such interfaces.Proceedings Title
